FRANK RHIND, OF BROOKLYN, NEW YORK.

LAMP- BASE.

SPECIFICATION forming part of Letters Patent No. 248,504, dated October18, 1881. Application filed August 10, 1881. (Model.)

To all whom t may concern:

Be it known that I, FRANK RHIND, of Brooklyn, in the county of Kings andState of New York, have invented certain new and useful Improvements inLamp-Bases, and I do hereby declare the following to be a full, clear,and exact description of the invention, such as will enable othersskilled in the art to which it pertains to make and use it, referencebeing had to the accompanying drawings, which form part of thisspecication.

My invention relates to an improvement in lamp-bases; and itconsists inmaking the base out of clay, which is first pressed into molds, baked,and then japanned, as will be more fully described hereinafter.

The object of my invention is not only to substitute a lighter and acheaper material for the bases of lamps, but to produce a base fromwhich the japan or coloring material cannot be chipped oi', as is thecase with iron.

Figure 1 is a perspective of one of my bases by itself. Fig. 2 is avertical section ofthe saine, showingl the base-ring of the standard inposition upon it.

Heretoforethe bases forla m p-standards have been made of iron, whichhave rst to be cast and then polished olf, so asto receive the japan. Asthe iron is not porous, the japan merely adheres to the outer surface,and is very readily chipped and broken off, so as to deface theappearance ofthe lamp to a very great degree.

rlo form my base I take clay of any suitable kind, which is firstpressed in a mold, baked, and then japanned. As the clay is very porousthe japan is absorbed by itto such a degree that it is impossible tochip any of the japan 0E without breaking the base itself.

Laying aside thc fact that an iron base always rusts where it isleftunprotected, or where the japan is chipped off ofit, a base madefrom clay is not only lighter and cheaper, but is equally asserviceable, and cannot have the japan chipped off, as is always thecase where the base is made ot' iron. Y

Through the center of the base, which is formed ot' clay, is made asuitable opening, B, for the standard -rod to pass through, and aroundthis hole is made a suitable recess or depression, I), in which thelower ring, F, of the standard tits. This ring F is stamped up from anylight sheet metal, and is placed upon the top of the base in the recessprepared for it, and then thc standard is placed upon this ring andclamped in position in the usual manner.

Having thus described my invention, I claim- As a new article ot'manufacture, a base for lamp standards, which is made of clay that ismolded into suitable shape, baked, and then l japunned, substantially asset forth.

2. A lamp-base made of clay or other porous material which will absorbthe japan to such a degree that the japan cannot be chipped oli' Withoutbreaking the base, substantially as described.

In testimony whereofI affix my signature in presence of two witnesses.

FRANK RHIND.
